Excavating Adventures Pro Tip: Swap out one big toy dinosaur for an assortment of small plastic dinosaurs. You can often find a pack of a dozen or more at your local dollar store for super cheap. The small dinosaurs can also be used to decorate the surface of your DIY Dinosaur Excavation Activity to give the dig kit a cool Jurassic world feel.

  1. Place the dinosaur in the plastic container.
  2. Mix 3 cups sand with 1 cup Plaster of Paris.
  3. Add 1 cup of water and mix until you have a pancake batter consistency.
  4. Pour the mixture over the dinosaur.
  5. Make another batch of mixture if needed to cover the dinosaur and fill the excavation. 
  6. If the dinosaur tries to float to the surface of the excavation, simply allow the excavation to set for a few minutes and then push the dinosaur back below the surface. The mixture will firm up and hold the dinosaur. 
  7. Place the DIY Dinosaur Excavation Activity in front of a fan overnight until it is completely dry.
  8. Distribute the excavation, excavation tools, and safety goggles to your Excavating Adventurer and have fun watching them dig in and discover the awesome dinosaur you have hidden inside.
